The overwhelming dominance of Democrats among US college faculty is consistent with a number of hypotheses, including
* leftists are overwhelmingly smarter than everyone else
* colleges have been captured by leftist ideology and literally discriminate against non-leftists in hiring and tenure-track
* Republicans were DEI hires in the 1960s and earlier, but now hiring is based purely on talent, so no Republicans are making it
* Conservative or moderate centrists find academia overwhelmingly hostile to them and choose other paths
* etc
Some of these possibilities are more probable than others, but I'm sure BriBri thinks it's the first and only that.
